Why teams connect AWS Aurora PostgreSQL and Couchbase

Keep AWS Aurora PostgreSQL and Couchbase synchronized in real time, across engines, regions, or services, in one or both directions.

Two databases that must agree is one of the oldest problems in engineering: different engines for different workloads, separate services with overlapping reference data, a migration in flight, or regional instances that share a subset of records. Hand-rolled replication across systems means change capture, conflict handling, and type mapping, all built and maintained by your team.

Stacksync syncs tables or collections between AWS Aurora PostgreSQL and Couchbase continuously and bi-directionally, translating types between the two engines and resolving conflicts by rules you configure. Rows written on either side appear on the other within seconds.

Common use cases

  • Keep a customer-facing Aurora database aligned with an internal admin tool, with writes accepted on both sides.
  • Feed operational dashboards from a read replica while the writer handles sync traffic.
  • Stream document mutations via DCP into downstream systems so caches, search indexes, or warehouses stay current.
  • Two-way sync between Couchbase (serving application data) and a CRM so support and sales teams see live application state.

Shared reference data between services

Services that own separate databases stay consistent on the records they share, without a custom replication layer.

Regional or environment copies

Mirror selected tables to another region or environment continuously, filtered to just the rows that should travel.

Cross-engine sync

Keep the same dataset live in both AWS Aurora PostgreSQL and Couchbase, so each workload runs on the engine that suits it.

What you can sync between AWS Aurora PostgreSQL and Couchbase

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

AWS Aurora PostgreSQL objects Couchbase objects
Views and materialized views Usable as read-only sources for filtered or precomputed sync datasets. Collections Table-like groupings of documents that syncs typically map one-to-one to destination tables.
Foreign keys Relationship metadata that syncs can translate into object references elsewhere. JSON Documents The core records; schemaless JSON keyed by document id, flattened or mapped to relational rows in syncs.
Replication slots and publications The logical replication objects that power log-based CDC. Global Secondary Indexes Indexes that make SQL++ query-based extraction efficient.
Databases and schemas PostgreSQL's two-level namespace scopes which tables a sync connection targets. XDCR replications Cluster-to-cluster replication streams, useful context when choosing a sync source cluster.
Tables The core sync unit; rows are matched across systems by primary key. Full-text search indexes Search indexes over documents, relevant when syncing searchable content.
Rows Inserted, updated, and deleted in both directions during bi-directional syncs. Buckets Top-level data containers, roughly analogous to a database, that scope replication and memory quotas.

How the AWS Aurora PostgreSQL and Couchbase connectors work

AWS Aurora PostgreSQL

Integration surface
SQL wire protocol (PostgreSQL-compatible), standard Postgres drivers and JDBC
Authentication
Database credentials, optionally AWS IAM database authentication, over TLS
Change detection
Log-based CDC via PostgreSQL logical replication (WAL decoding through replication slots), with timestamp polling as a fallback
Capabilities
read · write · CDC

Couchbase

Integration surface
SQL++ (N1QL) query service, key-value SDK APIs, and REST management APIs
Authentication
Database credentials with role-based access control, typically over TLS
Change detection
Database Change Protocol (DCP) streams document mutations; SQL++ polling on document fields as an alternative
Capabilities
read · write · CDC
Rate limits
Throughput is bounded by cluster sizing rather than API rate limits
